From what I have seen if you are a size 18 or over and having a baby you must be rich and wanting to spend a small fortune on a bra
I have been looking and here in Napier at the Warehouse, Farmers and Kmart the cheapest 20E bra that I have found is $40

and some places dont even go up to that price.
I got some 18DDs from the warehouse when they were $6 but my boobs are bursting out of them, the cups were too big before I got pregnant
Oh rant over, I'm off to bed now to read Harry Potter lol
